v3.3.3 · Übersicht: Master-Gruppe pro Typ (UI-only)

Integration: Title Classifier (title_classifier) — v3.3.3

UI-only: the Overview now groups watchers by context into one collapsible master block per type. Several watchers of the same context (e.g. Stash Slot 1..4) sit under a single "Stash" master header instead of loose flat cards.

STASH  ▾  4   Master · 2/4 aktiv · Enum 1
   ├ Stash Slot 1 · Overcharged Breeding · 1
   ├ Stash Slot 2 · River & Victor · 1
   ├ Stash Slot 3 · — inaktiv — · 0
   └ Stash Slot 4 · — inaktiv — · 0

Change

• New pure helper groupSourcesByContext (unit-tested): groups sources by context in first-appearance order and precomputes the master aggregate — total, active/online counts, highest active enum, active titles.
• Overview.tsx renders one collapsible master header per group (label · count badge · Master · X/N aktiv · Enum <max>); the existing WatcherCards (incl. inline enum/apply) are unchanged underneath.
• CSS for the group/header (styles.css). Frontend bundle rebuilt (vite).

Deliberately NOT in this PR

No new entity, no aggregate sensor, no downstream/contract/WS change — grouping is purely visual. (The "real aggregate master sensor" option was declined by the user for now.)
